The Health Security Agency has urged pregnant women to get vaccinated to protect their babies from birth as high levels of the infection continues.
An outbreak of whooping cough, which affects the lungs and breathing tubes and spreads very easily, began in November last year.
There have been 10 deaths from the infection in the UK since.
The number of cases of the infection has also risen above 10,000, according to UKHSA.
Latest data shows whooping cough cases peaked in May this year and high levels continued into June with 2,427 cases reported.
While most cases were in those aged 15 years or older, more than 300 have been reported in babies under three months, who are at greatest risk of dying or developing severe complications from the infection.
